LG Washer Error Code tE3

The tE3 code on an LG washer indicates an error with the duct condensing temperature sensor. The fault can be caused by an open circuit, a short circuit, a broken wire, or a connector that is out of place or making poor contact. The washer stops operation when this code appears to prevent damage from unmonitored temperatures. Checking the sensor and its connector is the recommended first diagnostic step.

A reset may temporarily clear the tE3 code, but if the underlying sensor or wiring fault still exists, the error will return once the washer attempts to run again. Unplugging the washer for a few minutes and restarting it can be useful as a first step to confirm whether the fault is persistent. A permanent fix requires inspecting and correcting the sensor, connector, or wiring issue causing the fault.

If the fix is simply reseating a loose connector, there is no parts cost involved. If the duct condensing temperature sensor needs replacement, the part itself typically costs in the range of $20 to $60 depending on the specific model. Adding professional labor, total repair costs can range from $75 to $200 or more. Diagnosing the exact cause first helps avoid unnecessary parts purchases.

In some cases, yes. Start by unplugging the washer and locating the duct condensing temperature sensor and its wiring connector. If the connector has simply come loose, reseating it firmly may clear the error. If the sensor or wiring is damaged, replacing the sensor is a repair that a confident DIYer with basic multimeter skills can often perform, though professional service may be preferred if disassembly is extensive.

It is not recommended to continue using the washer while the tE3 error is active. The duct condensing temperature sensor plays a role in monitoring heat within the machine, and operating without a functioning sensor means the washer cannot detect abnormal temperature conditions. Running the machine in this state could potentially lead to overheating or further component damage. The issue should be diagnosed and resolved before resuming use.
